IN THE BEGINNING: BARTER system was used as money says Sachin Karpe

Barter is the exchange of resources or services for mutual advantage, and the practice likely dates back tens of thousands of years, perhaps even to the dawn of modern humans. Some would even argue that it’s not purely a human activity; plants and animals have been bartering—in symbiotic relationships—for millions of years. In any case, barter among humans certainly pre-dates the use of money. Today individuals, organizations, and governments still use, and often prefer, barter as a form of exchange of goods and services says Sachin Karpe.
